Salesforce says it's added new machine intelligence features to its marketing cloud that will let marketers predict customer behavior.

The first feature, which Salesforce calls "Marketing Cloud Predictive Scoring," allows companies to score customers according to the likelihood of their taking steps toward some positive behavior -- like downloading an app or making a purchase.

Another feature, called "Predictive Audiences," allows companies to generate a list of customers with a certain score, and then devise a special plan for marketing to them. For instance, the company might isolate a group of customers who are exhibiting signs of falling out of touch, and undertake a marketing plan to win them back.

Salesforce said that companies Life Time Fitness and Rue La La are now using the predictive intelligence features. But Salesforce also told VentureBeat that it's a bit too early to show proof of success.

Salesforce says Predictive Scoring and Audiences will be included with the Salesforce Marketing Enterprise edition, and sold as an add-on to Pro and Corporate editions. Pricing starts at $125 per month.
